The following log message appears when LACP link fallback is enabled:
Feb 26 15:53:32: %STKUNIT0-M:CP IFMGR-5-NO_LACP_PDU_RECEIVED_FROM_PEER:
Connectivity to PEER is restricted because LACP PDU's are not received. Verify
the LACP configurations on PEER to bring up the Uplink LAG to attain better
bandwidth
The following log message appears when LACP link fallback is removed:
Feb 26 15:53:32: %STKUNIT0-M:CP %SMUX-5-SMUX_LACP_PDU_RECEIVED_FROM_PEER: LACP
PDU received from PEER and connectivity to PEER will be restored to Uplink Port-
channel 128.
Enabling the Verification of Member Links Utilization in a
LAG Bundle
To examine the working efficiency of the LAG bundle interfaces, perform the following steps:
1. The functionality to detect the working efficiency of the LAG bundle interfaces is automatically
activated on all the port channels, except the port channel that is configured as a VLT interconnect
link, during the booting of the switch.
2. Use the show link-bundle-distribution port-channel interface-number command to
display the traffic handling and utilization of the member interfaces of the port channel. The
following sample output is displayed when you enter this show command.
EXEC
Dell#show link-bundle-distribution port-channel
Dell#show link-bundle-distribution port-channel 1

Monitoring the Member Links of a LAG Bundle
You can examine and view the operating efficiency and the traffic-handling capacity of member
interfaces of a LAG or port channel bundle. This method of analyzing and tracking the number of packets
processed by the member interfaces helps you manage and distribute the packets that are handled by the
LAG bundle. The functionality to detect the working efficiency of the LAG bundle interfaces is
automatically activated on all the port channels, except the port channel that is configured as a VLT
interconnect link, during the booting of the switch. This functionality is supported on I/O Aggregators in
PMUX, Standalone, and VLT modes. By default, this capability is enabled on all of the port channels set up
on the switch.
You can use the show link-bundle-distribution port-channel interface-number command
to display the traffic-handling and utilization of the member interfaces of the port channel. The following
table describes the output fields of this show command.
